IMPROVEMENT IN' APPARATUS FOR GRAN ULATIN G SUGAR.

Be it known that I, F. MICHAEL, of Gratis, Preble county, Ohio, have made certain new and useful Improvements in Houses for Granulating Sugar;` and I hereby declare that the followingis atrue, full, and exact` description of the same, reference being had to'the accompanying drawings, and to the letters of reference marked thereon.. In the annexed drawings Which make a part of this specification- Figure 1 represents a front elevation of my sugar-hoi`se i Figure 2 is a plan view of the same with the top removed. p i

In fig. 1, A represents the sugar-house; 6 designates a girder, which binds the two s'idesof the house together in front. The gi'der 6 is strengthened by a series-of ties or joists, c, which are fastened at one end to girder-b, and at the other end firmly secured to the back ofA.. Under the ties e, and fastened to the back of A,

are the three conduits, d, which are held in a liorizontalposition by the brackets g, immediately above the top conduit d, and at right angles with cZ is placed the conduitf, which is supported by brackets to the end of A. The conduitf has an opening at its upper edge, and directly over conduit (Z, for the discharge of the ungranulated sirup into d. From d, the same sirup will flow through an'opening near the top of d, into the conduit c, which 'is directly under ol; and placed at the opposite end ofj, at the outer end of conduit'c, `an opening is left near its top for the flow of the sirup into conduit li, which projects a little-further outward than c. From c, the Birup flows into the second conduit d through an opening near the top of li, and near its inner end. The sirup into trough m, where the granulating process, if unfinished before, can be completed. Before the sirup is introduced into my sugar-house the following rules must be observe The juice of the sugar after ,being properly filtered will be boiled .to the consistency of forty degrees by the saccharometer, and afterit is thoroughly cooled must Vbeput into bhrrels. After remaining in barrels say ten days, it is prepared to go to the sugarhouse, when the barrels are placed on the ties e, so as to be convenient for discharging their contents into eonduitsf, and fromfflowing into the remaining conduits and 'into trough m, as already described. The discharge of the sirup or molasses from the barrel` must be regulated so as not to exceed a barrel in fortyeight hours. The molasses must be suffered to remain from three to eight days, or until the granulation is complete. During the process of granulation, the sugar-house should be kept at a temperature of not less than 80 nor more than 100 Fahrenheit. When the granulation is completed the sugar must be taken from the conduits'with shovels and put into sacks holding from twenty-live to thirty pounds, and after being thoroughly pressed, should be spread on a platform to remain forty-eight hours, with occasional stirring. It will then be ready for market.

Having thus described my invention, what I claim, and desireto secure by Letters Patent, is-

The conduitsfi c, it, L, K, d, and trough m, in combination with the sugar-housc A, the whole const'ucted arranged, and operating in the manner and for the purpose herein described.

In testimony that I acknowledge the foregoing as my own, I hereby aflix imy signature in the presence of two witnesses.
